Assessing Water Quality and Pollution Sources in the ‘KuneVain-Tale’ Lagoon

Abstract Water resources are of use for all categories in conditions where pollution indicators and toxins are within the approved national and international organisations that enable use as drinking water, agricultural water, or water discharged from economic activities, mainly industrial ones. Other studies, or those taken from the monitoring system at different levels, show that waters of rivers, lakes, seas and reservoirs in the country contain contaminating substances in values that damage the aquatic environment and reduce use values. From analyses performed in drainage hydrovore ‘Tale’, in the city of Lezha, at three monitoring points: before hydrovore, after hydrovore, and before the sea release for pH inductivity indicators, chlorides, sulphates, phosphates, nitrite, nitrates, ammonia, turbulence, dissolved oxygen, temperature, COD (chemical need for oxygen), coliform, Cu, Pb, Zn, and Cr. It turns out that at the points that we analysed, the parameter content is above the limits allowed for substances such as phosphates and heavy metals. At all three points, they have emerged above the permitted value, as well as high organic loads of BOD and COD. Like physico-chemical parameters and microbiological parameters (e-coli, coliform) indicate considerable faecal pollution. The study performed shows us the impact of urban and agricultural pollution as well as marine salts on water quality.
